👀 What Happened?

When trying to list emails using setup.sh outside of the docker container it does not work. I can create users with ./setup.sh email add , but ./setup.sh email list always fails with the error:

ERROR listmailuser: This command is only compatible with 'ACCOUNT_PROVISIONER=FILE'

In mailserver.env ACCOUNT_PROVISIONER is empty. The comments says defaults to FILE, changed to FILE, still fails.

This used to work on older versions. If I run from inside the container using:

docker exec -it <mailserver-container-name> setup email list

It works ok.

👟 Reproduction Steps

• Created new folder for install /opt/mailserver
• Created required folders in /opt/mailserver (docker-data/dms/config, etc.)
• Downloaded compose.yaml to /opt/mailserver/compose.yaml
• Downloaded mailserver.env to /opt/mailserver/mailserver.env
• Downloaded setup.sh to /opt/mailserver/setup.sh
• Edited compose.yaml and mailserver.env to set environment
• Executed /opt/mailserver/setup.sh email add , it works
• Executed /opt/mailserver/setup.sh email list - does not work
